Q:

What Divided by 43 Equals 81?

Accepted Solution

A:
What Divided by 43 Equals 81? Methods Setting up the problem: In a problem like this, the “what” means that we’re working with a variable. The most common variable used in math is “x”. So, we could say what number, x, when divided by 43, equals 81? Solving What Divided by 43 Equals 81 Here’s how you would set up this question as an equation: x 43 = 81 \frac{x}{43} = 81 43 x ​ = 81 The goal of the problem is to solve for x. To do this we need to change the equation so that x is alone on one side of the equation.In this case, we can do that by multiplying both sides of the equation by 43, resulting in this equation: x = 81 ∗ 43 x = 81*43 x = 81 ∗ 43 Then we simplify and find our answer: x = 3483 x = 3483 x = 3483 So, the answer to the question “What divided by 43 equals 81?” is 3483.To prove this, we can take the original problem: x 43 = 81 \frac{x}{43} = 81 43 x ​ = 81 And insert 3483 in the place of x: 3483 43 = 81 \frac{3483}{43} = 81 43 3483 ​ = 81 Because this is true, the answer must be correct.
